Interplate 317 Temporary Protective Primer is an inorganic zinc silicate paint used as a primer. The product is suitable for recoating with a variety of high-performance coating systems and is used in various environments (including offshore facilities, marine environments, chemical and petrochemical plants, power stations and bridges). A fast-drying two-component weldable zinc silicate shop primer, suitable for manual or automatic spraying. This product dries too quickly for accurate wet film thickness measurement; if a uniform film and surface roughness are not obtained, exposure to wind and sunlight will lead to rapid rusting. Parameters on this page: dry film thickness 10–25 µm (0.4–1 mil), theoretical spreading rate 18.67 m²/L, number of components: two-component.

All surfaces to be coated must be clean, dry and free of contaminants. Before application, all surfaces must be assessed and prepared in accordance with ISO 8504:2019.
Oil and grease shall be removed in accordance with SSPC-SP1 solvent cleaning. Where necessary, remove weld spatter and grind welds and sharp edges smooth.
Abrasive blast cleaning to at least Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation occurs between abrasive blast cleaning and application of Interplate 317, the surface shall be re-blast cleaned to the specified visual standard. Surface defects exposed by abrasive blast cleaning shall be ground, filled or treated by other suitable methods.
The blasted surface shall have an angular profile. The blasting medium shall be steel grit with a nominal particle size of 0.6–1.0 mm (24–40 mil), or a steel grit/shot mixture with a nominal particle size of 0.6–1.0 mm (24–56 mil).
This product is not recommended for hand-prepared steel.
| Mixing | Interplate 317 is supplied in two parts: a paste component (Component A) and a liquid base component (Component B). Add the liquid base (Component B) slowly to the paste component (Component A) while stirring with a mechanical stirrer. |
|---|
Do not add the paste component to the liquid component. Filter the coating before application and maintain continuous stirring during spraying. Once a unit of coating is mixed, use it within the specified pot life.
This is a low-viscosity material, and stirring is required during application to maintain uniformity.

| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International thinner. Once mixed, paint should not be resealed; if work is interrupted for too long, mix a fresh batch. |
| Cleaning | All equipment should be cleaned immediately after use with International GTA 803. Flushing spray equipment periodically during daily work is good practice. Cleaning frequency depends on the volume sprayed, temperature, spraying time, including interruptions, and other factors. |
All surplus paint and empty containers must be disposed of in accordance with the appropriate local laws/regulations.
Satisfactory welding performance can only be achieved by strictly controlling the coating at the recommended film thickness. Overcoating Interplate 317 increases fume during welding or cutting and increases weld porosity. Interplate 317 is a coating designed for automatic equipment; for small-area hand spraying, avoid dry spray and application of subsequent coats.
Note that this product dries too quickly for an accurate wet film thickness to be measured. If a uniform film and surface profile are not achieved, rapid rusting will occur on exposure to weather.
The drying times given apply to the recommended dry film thickness using an automated process at the stated temperature. Failure to follow these parameters may cause damage to equipment and rollers and cracking of the painted surface due to handling damage during stacking. Optimum results are obtained by preheating the steel substrate to 40 °C (104 °F).
The thicker the film of Interplate 317, the longer the corrosion protection provided, but welding, cutting and handling performance will be affected. In most environments, 25 µm (1 mil) is the recommended dry film thickness to achieve 6–9 months of protection.
When relative humidity is below 50%, satisfactory curing for recoating cannot be achieved within 24 h. Below 50% relative humidity, the curing process is severely hindered; water vapour or water spray may be required to increase relative humidity. This product dries too fast for accurate wet film thickness measurement. Early exposure of Interplate 317 to standing water can cause discolouration, possibly permanent. This affects only the surface appearance and does not affect the anticorrosive performance of Interplate 317.
For more spraying information and weathering performance, contact the International Paint Protective Coatings Division.
The product has the following approvals: • Welding quality – approval of pre-primer (LR) • Welding quality – shop primer for corrosion protection of steel plates and components (DNV) • Welding quality – weldable prefabrication shop primer (ABS) Note: VOC values are typical and for guidance only. The values may vary with colour differences and normal manufacturing tolerances.
Interplate 317 can be recoated in various systems and is suitable for steel protection in multiple environments.
